FEED-TROUGH.

SPECIFICATION forming part of Letters Patent No.369,022, dated August30, 1887.

' Application filed April 9, 1887. Serial No. 234,240. (No model.)

To all whom it may concern.-

Be it known that we, GEORGE W. MORGAN and SIMON P. HERE, citizens of theUnited States, residing at Oreswell, in the county of Keokuk, State ofIowa, have invented certain newandusefulImprovementsin Feed-Troughs, ofwhich the following is a specification, refcrence being had therein tothe accompanying drawings.

This invention has relation to feed-troughs, and is especially adaptedfor feeding hogs. The improvements will be more fully understood fromthe following description and claims, when taken in connection with theaccompanying drawings, in which- Figure l is a plan view of afeed-troughwith a part of the roof removed, showing our improvements. Fig. 2 is alongitudinal sectional view taken on the plane indicated by line 00 00,Fig. 1. Fig. 3 is a side elevation with a portion of the roof removed;and Fig. 4 is a cross-sectional view taken in the plane indicated byline y y, Fig. 1.

Referring by letter to the said drawings, A indicates the main frame ofthe structure, which is of a contour resembling the hogtroughs atpresent in use. This frame is composed of a suitable horizontal base, tothe 1011- gitudinal edges of which are secured ledges or vertical stripsa, forming the outer wall of the troughs E E. This base may be of anydesired length, and has secured to its opposite ends by close jointsvertical, end walls, 0, and these end walls, which are shown as beveledfrom a central point on their upper edges, are firmly connected at theirhighest points by a stout central longitudinal beam,

A. These end walls are obliquely grooved inwardly from their upper outercorners to form ways for gates or valves H, as will be presentlyexplained. The roof we have shown as made in two sections, R W, thesection W of which we have hinged to the longitudinal beam A to form adoor by which the food may be placedin the receptacle. Theseroofsections R and W are projected beyond the sides of the frame, asshown, so as to form a shelter for the trough.

The longitudinal beam A is provided with a suitable number of verticalapertures, b, for the passage of adj ustingscrews I. These arms of thecross-heads.

screws I have formed on their lower ends curved cross-heads J, the armsof which extend in opposite directions laterally, and are designed topass through apertures O in the gates or valves. The curved arms areplain, and the vertical screw L passes through the apertures in the beamA.

U indicates 1ever nuts on the adjustingscrews I, which are designed toraise and lower the said screws and consequently the valves or gateswhich are engaged by the The gates or valves H have their ends in theoblique grooves of the end walls, so as to assume a converging positionwithin the frame, and with the end walls, 0, form the hopper S. Thesevalves are provided with the transverse apertures O, to receive the armsof the cross-heads.

B indicates a clearing device, which we have shown as a strand of wire.This wire is socured at opposite ends to the vertical screws I above thecross-heads, and extends longitudinally within the hopper, so that whenthe levers U have been turned upon the said screws to open or close thevalves or gates this wire will also be moved, cutting its way throughthe feed in the hopper, thereby easing the discharge to the trough.

It will be seen from the foregoing description that the food placed inthe main receptacle will be fed automatic-all y into the troughs as itis consumed by the hogs, and the gates or valves may be regulated tofeed fast or slow, as desired.

It will be seen that by having the arms of the screws curved, as shown,there will be no obstruction to the movements of the gates, and thatthey may be raised from the bottom to the top of the frame. It will alsobe seen that by moving the levernuts the gates at both sides areoperated simultaneously.

Having described this invention, what we claim is- 1. The feed-troughdescribed, consisting of the main frame having the inwardobliquelygrooved end walls, and the longitudinal edge strips on thebase, the longitudinal top beam having vertical apertures, the inclinedvalves having transverse apertures, the adjusting screws having theirlower ends terminating in cross-heads having their curved arms in saidapertures, and lever-nuts for moving the said In testimony that we (10claim the foregoing screws, substantially as specified.
